I too am waiting for my cable.
For the Cruze, this is the Bulletin explaining the symptoms:
As the owner of a 2011-2015 model year Chevrolet Cruze vehicle, your satisfaction with our product is very important to us. This letter is intended to make you aware that some 2011-2015 model year Chevrolet Cruze vehicles may have a condition where the negative battery cable terminal clamp may have an insufficient crimp at the battery negative terminal. Over time, the internal resistance increases and vehicle electrical systems do not receive adequate power. With this condition, the following effects are possible: the Radio/HVAC Display may turn off and on; the Antilock Brake System, Service Traction System, Service Stabilitrac and Steering vehicle messages may come on and off; the turn signal sound may not be heard; “Battery Saver Active” and “Service Steering” may display in the Driver Information Center (DIC); and the interior and exterior lighting may flicker. Power steering assist may also be lost, and greater effort may be needed to turn the steering wheel at low speeds or while the vehicle is stopped.
